Chased by Sea Monsters – BBC

This gorgeous presentation explores the prehistoric world in search of sea-based monsters. More than just another dinosaur guide, Chased By Sea Monsters focuses on life in ancient oceans during each prehistoric period, providing a fine focus on evolutionary proceedings.
Nothing, not the carnivorous dinosaurs of the past, nor the imagined sea serpents and monsters of maritime history, nor the great white shark, salt water crocodile, killer whale and leopard seal of today can compare to the horrifying hunters of the prehistoric oceans. You will feel a lot more comfortable about going out for a swim or an afternoon boat ride knowing that such behemoths are extinct today!The Dunkleosteus is school bus-sized armored fish with razor sharp bladed jaws for cutting through anything in its path. The mighty Liopleurodon is a true monster, largest and most powerful of the Pliosaurs. The deadly Mosasaurs where the real sea serpents of their day, and some where large enough to dispatch an adult tyrannosaur easily. The Basilosaurus, the first of the large whale species, is not a harmless plankton eater but a fearsome high speed hunter. And most frightening of all is the Megalodon, a gargantuan ancestor of the great white that makes its modern day relative look like a tuna.If you’re a paleontology buff like me or a fan of BBC’s Walking with Dinosaurs series, this series is for you. The digital designs of the monsters are excellent and very well realized. And the fun-loving Nigel Marvin provides a great narrative.
